Have carried out the installation of a SSD in the Macbook Pro 17 "(Early 2011) with the hardwrk Set. The annexed guide has been created for a 13er MBP and was not quite match my 17er, but also differs from cosmetic in nature and is even a few steps easier. All in all, one can imagine the differences derive itself or look at ifixit.com and in 30min is the matter carried out easily as long as you have a steady hand and a little understanding of fumbling on PC components. The tool set is in good quality and the portions are fit. However, if you resurrected the value for some sheet metal, electronics and plastics facing the scarce 50 Euros, one must shell out for one would rather not think about it too long after ... Conclusion of mine: "not bad", according to Amazon scale makes 3 stars.
